By Kim Bo-eunTwo of President Moon Jae-in's special envoys who met North Korean leader Kim Jong-un in Pyongyang, Monday, will head to Washington today reportedly with a message to President Donald Trump from Kim. Expectations are high that their visit will pave the way for much-needed dialogue between the U.S. and North Korea on the denuclearization of the Korean Peninsula.National Security Office chief Chung Eui-yong and National Intelligence Service Director Suh Hoon may meet with Trump. There is also the possibility that each will meet their U.S. counterparts, National Security Advisor Herbert MacMaster and Central Intelligence Agency director Mike Pompeo.In the talks with South Korean officials, North Korea showed a surprising shift in stance, stating it was willing to give up its nuclear weapons if the safety of its regime was guaranteed.It also expressed a willingness to hold dialogue with Washington about denuclearization as well as the normalization of relations between the two countries.Meanwhile, Chung told reporters Tuesday that the envoys "have an additional stance of North Korea that will be delivered to the U.S.," but did not specify what this is."This can be seen as reflecting North Korean leader Kim Jong-un's trust in the envoys," Yang Moo-jin, a professor at the University of North Korean Studies, said."It is possible that North Korea may have stated its intention to send envoys to Washington, or to release American citizens it is detaining," he said.In the meantime, the U.S. has shown a mixed response to North Korea's offer for talks."The statements coming out of South Korea and North Korea have been very positive," President Trump said. However, at the same time, he stated Pyongyang's offer may be a "false hope."U.S. Vice President Mike Pence said "The U.S. and our allies remain committed to applying maximum pressure on the Kim regime to end its nuclear program. All options are on the table and our posture toward the regime will not change until we see credible, verifiable and concrete steps toward denuclearization."In North Korean leader Kim's first meeting with South Korean officials since he took power in 2011, he also stated he accepted that the joint-military exercises between South Korea and the U.S. would take place in April, at their usual scale.This contrasts with Pyongyang's past denunciations of the exercises, which it has continuously demanded to be halted.The talks took place after Kim Jong-un's sister Kim Yo-jong invited South Korean President Moon Jae-in for talks in Pyongyang during her visit to the South for the PyeongChang Winter Olympics last month.The North and South agreed in Monday's meeting to hold an inter-Korean summit in late April. It will be the first time in 11 years for the leaders of the North and South to meet. Ties were strained during the two conservative administrations who took a hard-line stance toward the North before Moon took office.It is seen likely that Pyongyang-Washington dialogue will precede the inter-Korean summit, as both states are willing for talks, and North Korea expressed its intention to discuss the issue of denuclearization.Developments may be made after the envoys make their visit to Washington. After their U.S. visit, Chung will head to China and Russia, and Suh to Japan.Inter-Korean relations have made progress this year, after heightened tension on the Korean Peninsula due to a series of provocations by the North in 2017. Kim extended a rare olive branch, stating his willingness to send a delegation to the PyeongChang Games. North Korea's participation was confirmed after military drills between South Korea and the U.S. were delayed until after the winter sports event.
